About These Specifications

Specifications characterize the warranted performance of the instrument under the stated operating conditions.
Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 °C. Typical specifications are not warranted.

Input Characteristics

All input characteristics are DC, ACrms, or a combination unless otherwise specified.
Maximum switching voltage ……………………………. 30 V
Maximum switching current (per channel) ……….. 0.5 A
Maximum carry current (per channel)……………….0.5 A
Maximum RF power ………………………………………..10 W

Caution The switching power is limited by the maximum switching current and the maximum voltage. Channel to common switching power must not exceed 10 W.
Note National Instruments recommends against switching active RF signals. As a relay actuates, the channel is momentarily unterminated. Some RF sources can be damaged by reflections if their outputs are not properly terminated. Refer to your RF source documentation for more information.
Note Switching active RF signals below 0 dBm may degrade signal integrity and decrease relay life.
For more information about switching active RF signals visit ni.com/info and enter Info Code RFSwitching.

Typical DC path resistance
Initial…………………………………….<0.35 Ω
End-of-life……………………………..≥1.0 Ω

Path resistance is a combination of relay contact resistance and trace resistance. Contact resistance typically remains low for the life of a relay. At the end of relay life, the contact resistance rises rapidly above 1.0 Ω.

RF Performance Characteristics

Voltage standing wave ratio (VSWR)
≤1 GHz………………………………….<1.25 (<1.1)
≤2 GHz………………………………….<1.5 (<1.3)
≤2.5 GHz……………………………….<1.75 (<1.5)

Typical isolation
≤1 GHz………………………………….>47 dB
≤2 GHz………………………………….>40 dB
≤2.5 GHz……………………………….>40 dB

Typical channel-to-channel skew ….<25 ps
Typical propagation delay ……………1.0 ns
Typical rise time (10% to 90%) ……75 ps
Refer to Figures 1, 2, and 3 for typical insertion loss, typical VSWR, and typical isolation, respectively.

Figure 2. Typical VSWR

Figure 3. Typical Isolation

Dynamic Characteristics

Maximum relay operate time………. 10.4 ms

Note Certain applications may require additional time for proper settling. For information about including additional settling time, refer to the NI Switches Help.

Expected relay life
Mechanical …………………………… 1 × 10 6 cycles
Electrical………………………………. 3 × 10 5 cycles
(30 V, 10 mA, DC resistive)

Trigger Characteristics

Input trigger
Sources ………………………………… PXI trigger lines 0–7
Minimum pulse width………………… 150 ns

Note The NI PXI-2554 can recognize trigger pulse widths less than 150 ns by disabling digital filtering.
For information about disabling digital filtering, refer to the NI Switches Help.

Output trigger
Destinations ………………………….. PXI trigger lines 0–7
Pulse width …………………………… Programmable (1 µs to 62 µs)

Physical Characteristics

Relay type ………………………………… Electromechanical, latching
I/O connectors…………………………… 5 mini-75 Ohm SMB jacks, gold plated
PXI power requirement………………. 3.7 W at 5 V, 0.3 W at 3.3 V
Dimensions (L × W × H) ……………. 3U, one slot, PXI/cPCI module 21.6 × 2.0 × 13.0 cm (8.5 × 0.8 × 5.1 in.)
Weight……………………………………… 204 g (7.2 oz)

Environment

Operating temperature ……………….. 0 °C to 55 °C
Storage temperature …………………… –20 °C to 70 °C
Relative humidity………………………. 5% to 85%, noncondensing
Pollution Degree ……………………….. 2
Maximum altitude……………………… 2,000 m
Indoor use only.

Shock and Vibration

Operational Shock……………………… 30 g peak, half-sine, 11 ms pulse (Tested in accordance with IEC 60068-2-27. Test profile developed in accordance with MIL- PRF-28800F.)

Random Vibration
